Trans-critical CO 2 system pushing boundaries for Meat World
O
ther than the production facility
in Springs, Meat World also has
a total of 15 stores. Meat World
CEO, Angelino Pereira, has worked with
the Coolcare (part of the Brasco Group)
team for 24 years and they look after
the refrigeration plants of the majority
of the stores. So, when the time came
to upgrade the production facility,
Coolcare was the natural choice.
In 2017, the experienced Coolcare
team received the plans for the new
Meat World production facility that was
going to be erected in the Springs area
for which they needed to supply energy
efficient refrigeration equipment at the
client’s request.

SYSTEM REQUIREMENTS
The new facility employs an impressive
370 staff, almost doubling the 180 in
number at the previous facility. It also
drastically increased in floor size, from
3 000m 2 to 7 000m 2 .

Due to the high
ambient temperatures
often experienced
in these parts of
South Africa, it was
vital that this system
could operate trans-
critically as well
as sub-critically.
Coolcare contacted Metraclark to
brainstorm ideas to supply technologically
advanced equipment that would save
their client energy, and deliver the
refrigeration specifications initially set out
for this massive facility. The Metraclark
engineering team worked off the floor
plans supplied along with all the daily
meat production figures and calculated all
the heat load requirements for each room.

The heat load for the system consisted
of amongst others between 80 and
160 tonnes of fresh meat as well as
1 000 tonnes of frozen meat passing
through the facility daily. This all
added up to a combined heat load of
840kW for both the medium and low
temperature applications. Additionally,
the client required that the system
could supply 10 000 litres of hot water
per hour as well as 2 000 litres of
chilled water for various factory and
processing functions.
Considering the requirement that the
system be state-of-the-art and energy
efficient, a standard synthetic refrigerant
refrigeration system was foregone in lieu
of a CO 2 system, incorporating a trans-
critical booster design. Due to the high
ambient temperatures often experienced
in these parts of South Africa, it was vital
that this system could operate trans-
critically as well as sub-critically.
The plant was commissioned in May 2018
and the new facility was fully moved over
and operational by 15 November last year.
